I need some advice😔

My husband and I are struggling in our relationship to the point I’ve been thinking about filing for divorce. We got married young (18&19) we are now 24 & 25. For the past 5 years we have done nothing but struggle financially because he doesn’t like to keep a job. Things always “happen” and he either quits or gets fired. I’ve held job after job and sometimes 2 full time jobs to try and keep my family afloat. My depression and anxiety have gotten so bad this past year to the point my mother and sister each made sure they spoke to me all day to make sure I was okay, because I was spiraling down so badly. I have given him chance after chance to change. He always tells me he’s sorry for the shitty life hes given me and my son. That he’s going to do right by me and be the husband he knows I deserve. Fast forward 3-4 months later we are back to square one. Same shit all over again. I love him dearly but this isn’t the kind of life I want for me or my son anymore. I just don’t know what to do.
